Description

A class (called “FS”) in TypeScript, that takes a directory as an argument which will act as an interface to a file system.

We need two methods in this class:

store(filename, content): Stores the content in filename within the given directory

get(filename): Returns the content from the filename

However, people are writing the same data over & over, but using different file names. So instead of storing the content as a file using the given filename, store the content using the hash of that content.

Let’s assume md5 is a "perfect" hashing function md5("content") -> "abcdef123456"

filename - only alphabetical characters

Example usage:

fs = FS("/topdir")
fs.store("filename1", "a very long string1")
fs.store("filename2", "a very long string1")
fs.store("filename3", "a very long string3")
result1 = fs.get("filename1")// gets 'a very long string1'
result2 = fs.get("filename2")// gets 'a very long string1'
result3 = fs.get("filename3")// gets 'a very long string3'

In the previous example the “a very long string1" is stored only once because two different files have the same content.

CI/CD (optional)

Write a short description of how would you deploy your solution in a cloud environment (AWS, Azure, GCP). What type of resources would you use and why?
